CONVERTIBLE SOFA Application filed May 16, 1917.

T0 all whom it may concern.'

Be it known that I, OSCAR FIGHTENBAUM, a citizen of the United States, and resident of Brooklyn, -in the county of Kings and State 0f New York, have invented certain new and useful Improvements in Convertible Sofas, of which the following is a speciication.

This invention relates to convertible sofas, and has for its general object to provide an improved locking means for securing sections of the bed together and which may beV automatically actuated during the operation of converting the device from a sofa into a bed, or vice versa.

To these ends the invention further consists in the novel details of construction and combination of parts more fully hereinafter described `and particularly pointed out in the claims.

Referring to the drawings forming a part of this specification, in which like numerals designate like parts in all the views- Figure 1 is a vertical longitudinal sectional view showing the sections of the bed frame unfolded. l

`Fig 2 is a detailed slde elevational view of a portion of the frame, showing the mechanism for locking the movable sections one to the other when these are folded, and Fig. 3

and is arranged to be swung upwardly and rearwardly and to be held in its upper position by means of the latch bar 8 engaging the keeper 9.

The frame b consists of a stationary section 10, an intermediate section 11, and an end section 12. The stationary section 10 is rigidly secured to the housing a between the ends thereof and is herein shown as being formed of angle iron, and carries at its outer corner portionsthe uprights 13 and 14:. The side rails, one of which is shown at 15, of the intermediate section 11, are pivotally Patented Jan. 7, 1919.

connected as at 16 to the upper end of the uprights 14, and link connections, one of which is shown and indicated by 17, are made between the adjacent ends of the side rails 15 andthe side rails 18 of the end sec"- tion 12.

The section 12 is made shorter in length than the section 11, and the link-connections 17 are so proportioned in length'as to correspond approximately to twice the thickness of the mattress, so that when section 12 is folded onto section 11 the rails 18 of the former will be parallel to the rails 15 `of the latter, as shown Iby dotted lines in Fig. 1. When the section 12 is folded onto the section 11, as just described, the uprights 18 positioned at the ends o-f the foot-rail 19 bear on the rails 15 of section 11, in the notched portions 20, as shown.

The length of the section 11 is greater than the corresponding dimensions of section 10, so that when the sections are folded to form a sofa, the ends of the side rails 15 will bear on the upper end of the notched or cut-away portion 21 of the uprights 13 of the stationary section 10.

The seat 5 by means of the links 22 and 23 is pivotally connected to the side rails of the intermediate section 11, and the seat is arranged to move relatively to said section during the initial movement thereof and to be held suspended therebeneath when the section is unfolded.

In folding sections 11 and 12 onto section 10, as shown by dotted lines in Fig. 1, slidable latch bolts, one of which is shown and indicated by 24, on the side rails 15, are arranged to engage with the uprights 18.

This engagement between the latches and uprights has the effect of locking the sectionsll and 12 one to the other, as these move toward section 10. The latch bolts are held against detachment from the rails 15, by pins 25, `which pass through slots 26 in said rails, and by means of pivoted links 27 connecting the latch bolts with the links 22 for connecting the seat to the section 11, the latch bolts are automatically brought into and out of engagement with the uprights 18 when the sections 11 and 12 are unfolded or folded onto the section 10.

One end of the spring 28 is connected to the footrail 19 and the opposite end of said spring is connected to a head rail 29. A pair of arms, one of which is shown at 30, are connected to the head rail 29 and are pivotally connected as indicated at 31 to a pair of rods, one of which is shown at 32, secured to the frame 10. When the sections 10, 11 and 12 are folded one upon the other, the head rail 29 bears on the portion 29 of the frame 10, but, when the said sections are unfolded the head rail 29 is elevated into the plane of the rails 15 and 18. The elevation of the head rail is caused by the movement of the unfolding of the sections when the device is opened to form a bed. A pair of chains, one of which is shown and indicated by 33, prevent upward movement of the head rail beyond the position just stated. W'hen the sections are folded one upon the other, the spring 28 is relaxed, but the unfolding of the section 12 operates to tension said spring, due to the fact that the chains 33 operate to hold the head rail 29 against upward and outward movement during outward and downward movement necessary to adjust section 12 into horizontal alinement with Section 11'l vVit-h respect to the position of the parts as indicated at Fig. 1, it will be observed that the outer end portions of the rails 11 are provided with rigidly attached supports, one of which is shown at 34. The `ends of these supports come into contact with the iioor and operate to support the section 11, when the same is unfolded, and link connections, one of which is shown at 35, eX- tend between the lower ends of the supports 34: and the supports, one of which is shown at 38 of section 12. The supports 3G are pivotally connected to the rails 18 and the links operate to fold and unfold said supports during the folding and unfolding of the section 12. When the section 12 is unfolded, the links 35 cooperate with the supports 34 and 36 to provide a support common to the sections 11 and 12.

When the parts are in the folded position, the device is used as a sofa, and it may be converted into a bed by causing the said back to move upwardly and outwardly until the latch bar 8 engages with the keeper 9. In this position of adjustment of the back, a suflicientspace is afforded to permit the operator on taking hold of a convenient portion of the section 11 to unfold the same and section 13 to the posit-ion shown by dotted lines in Fig. 1. During the unfolding of the sections.V as just described, the latch bolts are disengaged from the uprights 18, so that the end section may be unfolded and the device convertedV into a bed. In converting the device into a sofa, section 12 is folded onto section 11 and the said sections 11 and 12 are then folded onto section 10, and the back 6 is then permitted to descend to engage the upper face of the rear end portion of the seat, after first disl. In a combined bed and sofa, the combination of a sectional folding bed frame, including a stationary section, an intermediate section and an end section, a movable seat mounted on said frame, uprights mounted on said end section and adapted to engage the intermediate section for holding said sections in spaced relation when folded, latches mounted on the intermediate section adapted to engage the uprights and to be actuated by said seat for locking said intermediate and end sections one to the other when the frame is being folded.

2. In a combined bed and sofa, the combination of a sectional folding bed frame, including a. stationary section, an intermediate section, and an end section, a movable seat mounted on said frame, uprights mounted on said endsection, and automatic locking means positioned at the sides of the intermediate section and adapted to engage the uprights and to be actuated by the seat for locking said intermediate and end sections one tothe other when the frame is being folded.

Signed at New York, in the county of New York and State of New York this 12th day of MayA. D. 1917.
